【摘要】 随着土地科学研究的深入和全球人口、资源与环境问题的发展变化,旨在更好地掌握土地质量变化的土地质量指标体系(LQIs)研究被土地科学研究领域中最为活跃的几大国际组织确定为优先研究项目。1995年开始实施的LQIs项目虽然取得了相当的进展,但是要成为国际标准仍然有许多工作要做,除了养分平衡与增产潜力两项指标比较成熟,其它指标都需要进一步的深入研究。
【Abstract】 More recently, in an attempt to better understand the changes in land quality, LQIs has been the prior field for many international organizations, as the land science goes further and global population, resources and environment issues change. From 1995, although we have been made much advance in LQIs research, much remains for LQIs research to be done to develop into an international standard, in this paper, we review the advance in LQIs research based on the LQIs system of World Bank.The core LQIs encompass three types: Core LQIs identified for immediate development are nutrient balance, yield gap, land use intensity and diversity, and land cover; LQIs requiring longer term research include soil quality, land degradation, and agro-biodiversity; LQIs being developed by other authoritative groups include water quality, forestland quality, rangeland quality, and land contamination/pollution. Among these 11 indicators, research on nutrient balance and yield gap are fairly mature, others remains further work to do.
